CROSS-REFERENCE TO RELATED APPLICATION

This application is a Nonprovisional of, and claims priority to, U.S. Patent Application No. 61/535,095, filed Sep. 15, 2011, entitled “DEVICES AND METHODS FOR MANIPULATING BODILY TISSUES”, which is incorporated by reference herein in its entirety.

BACKGROUND Field

The present invention generally relates to medical devices and procedures, particularly devices and methods used during surgery/operation for the treatment of pelvic organ prolapse.

Various types of tissue manipulators are used for manipulating pelvic and other organs to facilitate access to their anatomical structures during surgical procedures. A vaginal manipulator is one such manipulator that can be introduced into a vagina for manipulating vaginal tissues. Several vaginal manipulators are available to help maneuver the vagina, facilitating proper dissection in the pelvis. The purpose of some vaginal manipulators is to move the vagina around so that it is easier for dissection and placement of various medical devices such as slings. The vaginal manipulator may also act as a backstop for suturing during abdominal/laparoscopic pelvic floor procedures.

Various shapes of vaginal manipulators are available to meet the requirements of surgery. Some existing manipulators used in pelvic surgeries are round or cylindrical in shape at their distal ends and are configured to contact the vaginal tissues. It can become difficult to suture the bodily tissues with these round and cylindrical shapes at the distal ends. For example, they may provide a relatively small area for manipulation and maneuvering. This can also result in the device not functioning as a positive stop during suturing applications.

Further, the anatomy of the vagina may be wide and may not be completely cylindrical. It is well known that the vagina is relatively long, hollow, and has a tube like structure that extends from the cervix or the outer end of the uterus down to the labia minora. Hence, the round or cylindrical manipulator may not be preferably shaped to cooperate with the shape of the vagina completely. As per the surgical requirements and also considering the anatomy of the vagina, the existing manipulators therefore may not be suitable to comfortably and easily repair pelvic damage. In addition, certain other features such as easy visualization and a wide range of angular manipulation of the manipulators may also be required for an efficient surgical procedure.

Thus, there is a need for an improved medical device/manipulator having a shape that suits the vaginal anatomical structure, provides easy visualization of bodily tissues during surgical processes, and can operate at a wide range of angular adjustments.

SUMMARY

A medical device and a method for manipulating bodily tissues are described. The medical device includes an elongated portion having a proximal end portion and a distal end portion. The elongated portion has a defined width referred to as first width. The medical device further includes a head portion extending from the distal end portion of the elongated portion. The head portion includes a first flat surface on a first side and a second flat surface on a second side opposite the first side. The head portion has a defined width referred to as the second width. The second width is greater than the first width.

FIG. 1 is a schematic diagram of a medical device 100 configured to manipulate a bodily tissue. The medical device 100 includes an elongated portion 102 and a head portion 104 extending from the elongated portion 102. In accordance with some embodiments, the medical device 100 can be a vaginal manipulator configured to manipulate vaginal tissues.

The elongated portion 102 includes a proximal end portion and a distal end portion. The elongated portion 102 has a predefined width referred to as first width. The elongated portion 102 may also include a handle at its proximal end portion ergonomically designed to be gripped by an operator or a surgeon. In certain embodiments, the elongated portion 102 may be cylindrical in shape having a circular cross section at the distal end portion and the proximal end portion. In other embodiments, the elongated portion 102 may be shaped such that the cross section is rectangular, or square, or any other shape at its distal end portion and the proximal end portion. Similarly, various other shapes of the elongated portion 102 are possible. For example, the cross section of the proximal end portion and the distal end portion can be pentagonal, hexagonal, octal, and the like. In accordance with some embodiments, the width of the elongated portion 102 is uniform from the proximal end portion to the distal end portion. In accordance with other embodiments, the elongated portion 102 may be tapered having the first width at the distal end portion. In some embodiments, the elongated portion 102 is flexible in nature. In other embodiments, the elongated portion 102 is rigid.

The head portion 104 extends from the distal end portion of the elongated portion 102. The head portion 104 has a second width such that the second width is greater than the first width (of the elongated portion 102). In this manner, the head portion 104 projects/bulges laterally from the elongated portion 102 and provides even a larger surface area for tissue manipulation through the head portion 104.

The head portion 104 includes a first flat surface on a first side of the head portion 104 and a second flat surface on a second side opposite the first side. In some embodiments, the first flat surface and the second flat surface have greater width than the first width (of the elongated portion 102). In some embodiments, the first flat surface and the second flat surface have width equal to the width of the head portion (second width). The first flat surface and the second flat surface are configured to provide a larger surface for manipulation of the bodily tissues such as the vaginal tissues. This helps maneuver the vagina to facilitate proper dissection in the pelvis. The purpose of the flat surfaces of the vaginal manipulator is to move the vagina around so that it is easier for dissection and placement of implants such as slings. The first flat surface and the second flat surface also act as a backstop for suturing during abdominal/laparoscopic pelvic floor procedures. The first flat surface and the second flat surface can also be used to spread the bodily tissue to facilitate suturing at a correct location. It must be appreciated that either of the first flat surface and the second flat surface can be used one at a time for manipulation. In some embodiments, the surgeon/operator may use the first flat surface to suture on anterior portions of the vagina and the second flat surface to suture on posterior portions of the vagina.

In certain embodiments, the head portion 104 and the elongated portion 102 form an integral part of the complete medical device 100. In some other embodiments, the elongated portion 102 and the head portion 104 can be removably attached with one another. The head portion 104 can be coupled to the elongated portion 102 through welds, arms, prongs, clips, and other fastening mechanisms.

In some embodiments, the coupling/attachment of the head portion 104 with the elongated portion 102 may not allow relative motion between them. In other embodiments, the elongated member 102 can be coupled to the head portion 104 through a pivot joint such that relative motion between the head portion 104 and the elongated portion 102 is possible. This may assist in manipulation of the bodily tissues.
